Creating a virtual slave

Additional virtual slaves can be created on the same hardware interface. This enables more data to be exchanged with a PROFIBUS master, or a connection with a second PROFIBUS master can be established.

A maximum of four virtual slaves can be created. A maximum of 240 bytes of data can be configured per slave, i.e. a total of four times 240 bytes of data can be exchanged in each direction. Each virtual slave receives its own address via TwinCAT and is configured for the PROFIBUS master as an independent device.

Proceed as follows:

1. Right-click on a PROFIBUS slave in the tree view on the left.

2. In the context menu click Add New Item.

A further box (virtual slave) is created. Up to four virtual slaves can be created.

You can now create your own variables for the virtual slaves and set the PROFIBUS addresses.
